    assume this is fixed now, did you need a new engine. I've just been told I need one for the same fault, 9500 pounds !

If motor is making a ticking noise, what can be done?


It is normal for engines to develop ticking noises as they age. The valve lifters are usually hydraulic and can change ability to hold fluid as tight as when new, cams and cam followers can wear down. The cost to remedy a slight tick is not worth it.

2006 cts 2.8 making loud ticking noise ,running rough and has misfire codes po300,301,303,305


codes p 300 is a random/ multiple misfire===causes spark plugs---HT leads ---injectors/s--ignition coil/s--low compression---wiring
codes p 301,303,305 are misfires detected for no 1,3 5 cylinders === causes listed are engine mechanical fault---wiring---ignition/fuel systems ---injectors---ECT/MAF sensors---ECM
You do not mention if this is a v6 engine in which case no 1,3 5 will be all in the one bank head
With the loud ticking noise that amounts to a mechanical fault associated with that bank
could be loose valve seat inserts , cam lobes failure or cam follower failure or hydraulic lifters problem even loose cam shaft bearings / caps
I would be inclined to remove the rocker cover and check for metal , loose bolts , excessive valve clearance before I went plugs etc
the main indicator for the answer is the loud ticking noise which indicates a valve train problem which will cause the rough running

Lifter noise lexus ls430 2001


Lifter noise(s) can be a combination of things........ 1. High mileage on engine. 2. Not using the correct oil. 3. Lots of sludge build up in motor due to lack of oil changes and the quality of oil that you are using. Hydraulic lifters rarely fail but it does happen, given the conditions on how the car was maintained. I can offer you a solution but no guarantees on what might quiet this lifter down. It's a 50/50 chance. On your next oil change, I would recommend taking your vehicle to a facility that sells BG products. It's a company that formulates chemicals that have great cleaning properties to your fuel system and oil lubricating systems in your engine and at the same time, it is safe on all rubber seals in your engine. (Especially Higher Milage Vehicles) Ask for BG MOA to be added in you next oil change or if you do your own oil changes, you can find this product on line and can purchase from there. What the BG MOA does, it helps break up sludge and build up on the inside of your engine and helps to free up your valves, piston rings and noisy lifter(s). Hydraulic lifter(s) tend to make noise when they can't sufficiently pump up with oil due to sludge and build up blocking the oil inlet passage. Worn lifters on cold start up may be very noticeable but eventually the ticking goes away after engine warms up and the hydraulic lifter(s) had time to pump up. Make sure that you don't have a exhaust manifold leaking as well due to a crack or a failing exhaust manifold gasket. This can also emit a ticking noise in which can be misdiagnosed for a ticking lifter. A leaking exhaust manifold can usually be identified by the ticking noise getting louder and faster when accelerating and quieter and slower when decelerating. Ticking noise is loud on cold start ups but not noticeable at all when engine is at operating temperature. Hope this will help you out.

Tikking noise coming from engine


Yes, you're right, those could be the cause. Also, possible it's a collapsed hydraulic valve lifter, if your car has hydraulic operated (from engine oil) valve lifters. At any rate, it sounds like something loose in the valve train-valve lifter with push rod engines; or cam followers {rocker arms) with overhead cam engines that push on the top of valve stems .
Check a repair manual to see if your engine has valves that can be and need adjusting. Engines with valve lifters do not require periodic adjustment for proper valve clearance. Engines with rocker arms do require checking the valve clearance every couple of years or so.

Top of the engine is ticking. friend told me it could be a valve that is clogged or stuck open and thats its not a huge problem but it might be mixing gas and oil. to me that sounds like a problme....


It sounds like hydraulic lifter noise. The lifters open and shut the valves and can be helped by using a good synthetic oil and frequent oil changes. Lash is the clearance between the valves and lifters.

Is it necessary to replace valve lifter or can you adjust lash to reduce clatter on dakota v-8


hydraulics lifters you must replace as they will wear out.

solid tappet lifters can just be adjusted for. Unless you have some custom old engine in yours I'd imagine yours is the first.

You might also try running some pennzoil or quaker state oil to reduce clatter. They're wax based and will often do wonders for semi-clogging the right areas while keeping the other places open. Great for hi mileage motors.

Tappet valve noise added 20w50 oil and rislone engine treatment still ticking or clapping


It needs a valve adjustment or a complete valve job a mechanic can tell. (I had a 94 same noise, traded it in!)

Ticking coming from right bank replaced the 2 i thought but still is ticking


You really did not explain at all. What was ticking? It could be injectors, valve lifters, etc.?

If it is fuel injectors, they are supposed to tick.
It is when they don't tick that you worry about them.

If it is valve lifters, then you need to try adjusting them. They may be hydraulic, but still could be beyond the range the oil can account for.

Let us know more, and we can explain more.

Valve tick on one cylinder that tick intermitenly,thicker oil


There was a "Silent Recall" for this problem. Basically the heads, lifters, and cam are all replaced. I had this fixed under the recall on 1995 Pathfinder when it had 44,000 miles on it. Now it has 175,000 and has been had the cold engine noise since 145,000. The ticking is more irritating that it is harmful (Per my mechanic). I don't want to stick 1,000's of dollars into it anymore, tolerance is much cheaper.

Ticking noise from engine


You might have a bad hydraulic valve lifter (assuming this engine has them)... you could try an aftermarket product designed to unstick valve lifters.... any auto parts store carries them.
